Interface and Abstract Class Hai, When do we go for Interface. . When do we go for Abstract Class. . .Give one example Today i faced one interview . . He asked this question.I want answer with Example Thanks in Advance Abstract Class :: - It cannot defines all the methods - It has subclass. - Here, Subclass is useless - A class can be extend an abstract class Interface :: - It defines all the methods - It must have implementations by other classes, But there http: / / kyapoocha.com / c-sharp-interview-questions / what%E2%80%99s-the-difference-between-an-interface-and-abstract-class-5 / http: / / www.dotnetuncle.com / Difference / 4_abstract_class_interface.aspx Hope this helps. HI An interface contains signatures of methods , delegates or events . The implementation of the methods is done in the class that implements the interface, as shown in the following example: interface ISampleInterface { void SampleMethod(); } class ImplementationClass : ISampleInterface { / / Explicit interface member implementation: void ISampleInterface.SampleMethod() { / / Method implementation. } static void Main() { / / Declare
attribute like Summary, Keyword, Title, Author. . .etc. . . . without storing on the server. . . .

cannot be used with indexers, destructors, or types. In C#, the static keyword indicates a class variable. In VB, the equivalent keyword is Shared. Its scoped to the class in which it occurs. Example a. Static int var / / in c#.net b. static void theory this allows very tight interop between different .NET languages - for example allowing a C# class to inherit from a VB class. • 07. What is IL? • Ans : IL = Intermediate Language. Also known as MSIL (Microsoft Intermediate Language to in the context of Managed Extensions (ME) for C++. When using ME C++, a class can be marked with the _ _gc keyword. As the name suggests, this means that the memory for instances of the class is managed by the garbage collector, but it also means more than that. The class becomes a fully paid-up member of the .NET community with the benefits and restrictions benefit is proper interop with classes written in other languages - for example, a managed C++ class can inherit from a VB class. An example of a restriction is that a managed
